That is true for owners of Poser 9/2012, but who would police who has that, and who does not?

Also...as an example, the new CR2 references: 

C:...Poser 9 ContentRuntimeGeometriesWardrobeWizardAnastasia_WWFae Chest Armor_130991184.obj

This is not the original OBJ.  So, to make this work, you would need this OBJ.  If someone gave you this OBJ, you would not need to buy Fighting Fae.  That would be bad.

Probably best for someone to ask PhilC for the proper legalities here, as I am sure he has had these questions before.
